Losing Hope

I did a microgendx test in June and found out I have a high load of enterococcus faecalis. I’ve been taking biofilm disruptors and antimocrobials since then and also started hiprex last week. Three days ago I started experiencing extreme urethral burning so I thought it was a breakthrough infection due to everything I’ve been taking. I started Linezolid based off my microgendx results when the extreme uti symptoms started, so today is day 3. The burning is so still intense so I went to urgent care to make sure it wasn’t something else like an STI. Everything came back negative and no WBCs in urine. I’ve never had such burning this far into antibiotic treatment and I’m freaking out that this won’t improve. Has anyone experienced something similar?
